Polyaniline (PANI)/copper oxide (CuO), poly(3,4-ethylenedioxythiophene) (PEDOT)/CuO and polypyrrole (PPy)/CuO have been synthesized electrochemically on glassy carbon electrode in sodium dodecyl sulfate in sulfuric acid solution as an electroactive material. To our best knowledge, the first report on comparison of supercapacitor behaviors of PANI/CuO, PEDOT/CuO and PPy/CuO nanocomposite films was studied by electrochemical impedance spectroscopy, related to the plots of Nyquist, Bode magnitude and Bode phase. The highest specific capacitance (C sp ) was obtained as C sp = 286.35 F 9 g -1 at the scan rate of 20 mV 9 s -1 for PANI/CuO amongst the PEDOT/CuO (C sp = 198.89 F 9 g -1 at 5 mV 9 s -1 ) and PPy/CuO (C sp = 20.78 F 9 g -1 at 5 mV 9 s -1 ) by CV method. Long-term stability of the capacitor has also been tested by CV method, and the results indicated that, after 500 cycles, the specific capacitance of PANI/CuO nanocomposite film is 81.82 % of the initial capacitance. An equivalent circuit model of R s (C dl (R 1 (Q(R 2 W)))) has been used to fit the experimental and theoretical data.

In this paper, 6-(3,6-di(thiophene-2-yl)-9H-carbazole-9-yl)-hexanoic acid (ThCzHa) comonomer was newly synthesized and characterized with Fourier transform infrared spectroscopy (FTIR) and 1 H-NMR. The synthesized comonomer was electrochemically deposited onto carbon fiber microelectrode (CFME). An electrochemical impedance study on the prepared electrodes is reported. Poly(ThCzHa)/CFME is characterized by cyclic voltammetry (CV), Fourier transform infrared reflectance-attenuated total reflection spectroscopy (FTIR-ATR), scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDX), and electrochemical impedance spectroscopy. Capacitive behaviors of modified CFMEs were defined via Nyquist, Bode-magnitude, Bode-phase, and Admittance plots. The equivalent circuit model of R(Q(R(C (R(C(RW))))))(CR) was examined for polymer/electrolyte system. The effect of initial monomer concentration (0.5, 1.0 and 1.5 mM) on the formation of alternating copolymer is reported in 0.1 M sodium perchlorate/acetonitrile solution. The copolymer structure was also characterized by FTIR-ATR, SEM-EDX, and CV measurements. The highest low frequency capacitance (C LF = 5.2 mF cm

“…Conductive polymers have been electrochemically preferred because of their physical or chemical properties such as volume, color, stored charge or porosity and used for a number of applications such as electrochromic displays [1][2][3][4][5][6][7][8][9][10][11], smart windows [12], solar cells [13][14], supercapacitors [15][16] and biosensors [17][18]. 3,4-alkylenedioxythiophene based polymers exhibit low oxidation potential, high and quite stable conductivities, a high degree of optical transparency as a conductor, and the ability to be rapidly switched between conducting doped and insulating neutral states.…”

“…Side-chain derivatization is possible due to ProDOT flexibility of the conjugated backbone structure. The dimethyl and diethyl derivatives especially exhibit enhanced electrochromic contrasts throughout the visible region [21] and high capacitive behaviors [15][16].

“…Generally electrocoating of conjugated polymers on carbon fiber easily allows the characterization of the deposited films by spectroscopic, morphological and electrochemical techniques. Conducting polymers which were coated electrochemically onto CFMEs were studied in detail and reported by Sarac and coworkers [16,[26][27][28][29][30][31][32][33]. Electrochemical impedance spectroscopy (EIS) is a powerful technique to study charge transfer, ion diffusion and capacitance of conducting polymer modified electrodes [34][35][36][37][38][39].…”

Abstract. Electroactive random copolymers of 3,4-Propylenedioxythiophene (ProDOT) and N-Phenylsulfonyl Pyrrole (PSP) were electrochemically synthesized on single carbon fiber microelectrode (SCFME) by cyclic voltammetry (CV). Fourier Transform Infrared-Attenuated Total Reflectance (FTIR-ATR) measurements indicate the inclusion of PSP into the copolymer structure. The influence of feed ratios on the copolymers was studied by CV and electrochemical impedance spectroscopy (EIS) and equivalent circuit modelling (ECM). The morphologies and film thicknesses of copolymers were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The results have shown that the principal changes in morphology, conductivity, porous nature and thickness of Poly(ProDOT-co-PSP) film depend on the concentration of PSP. The strong electron-withdrawing sulfonyl group substitution on PSP significantly inhibited electrochemical copolymerization. Semicircular characteristics at Nyquist plots reflected an increasing trend with the increase of PSP concentration in the feed at high frequency. The semicircular characteristic of the copolymer film is useful for the bioelectrochemical sensor applications.
